CLOTH-NAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 561,220, dated June 2,1896.

Application filed September 19,1890. Serial No. 365,513. (No model.)

To all whom it may concern..-

Be it known that I, DAVID GEssNER, of WVorcester, in the State ofMassachusetts, have invented a new and useful Improvement inCloth-Napping 'Machines, of which the following is a specification.

My invention is applicable to napping-machines of the character referredto in Pat-ent No. 458,185, dated August 25, 1891, in which thenappingmollers are mounted revolubly on wheels or spiders that arefastened to the maincylinder-shaft.

One part of my invention consists in the construction of thenapping-rollers, and another part consists in the construction of themechanism for feeding the cloth to the napping-rollers.

In. the accompanying drawings, Figure 1 shows a port-ion of thenapping-machine frame and the mechanism by which the cloth is fed intothe napping-machine and two of the guide-rollers, each of which assistsin holding the cloth in tangential contact with the nappin g-cylinder.Fig. 2 shows one form of construction of the napping-rollers, on whichthe wires of the clothing substantially all incline in one axialdirection. Fig. 3 shows the companion roller of the above, in whichcompanion roller the wires of the clothing substantially all incline inthe opposite axial direction. Fig. 4. shows the construction of anapping-roller in which the wires on opposite sides of the centraltransverse plane incline substantiallyin opposite directions. Figs. 5,6, and 7 are details of the feeding mechanism.

The cloth enters the machine at 1 and pursues the course indicated'bythe dotted lines. It passes over roller 2, to which roller a1ongitudinally-reciprocatin g motion is imparted,

the object of which is to cause the cloth to pursue a zigzag course overthe nappers and thereby bring into play various napping-wires to asequal an extent as possible, so that the wear of the wires will be asnearly as possible from one end of the napping-rollers to the and fromroller 10, in tangential contact with the surface of thenapping-cylinder. As the cloth passes from the guide-roller 8 to theguide-rollerl0 it passes around the draft-roll 9, which is driven by anysuitable means.

The following mechanism (shown in Figs. 1., 5, 6, and 7) is employed forimparting a longitudinally-reciprocating motion to the roller 2: .Uponthe shaft 80 of the draft-r0119 is mounted a worm 81, which drives aworm gear 82, fixed on the shaft 83, bearing a crankpin 84, operating ina slotted piece 85. This slotted piece is pivoted at 86 and is prolongedon the opposite side of the pivot into the segment 87, which engageswith the rack 88, formed on the sleeve 89, which forms a bearing for theroller 2 and which is mounted so as to slide longitudinallyin thebracket 90.

The construction of the napping-rollers shown in Figs. 2 and 3 may bemore particularly described as follows: The barrels of the rollers arecovered with the usual fabric hearing the protruding wires 100. Thiscovering 'fabric,which is called clothing, is so placed,

however, that certain of the wires incline toward the opposite ends ofthe machine. In Figs. 2 and 3 this difference of inclination takes placebetween the wires on different rolls.

In Fig. 4: the dilference in direction is between the wires located onthe same nappingroller on opposite sides of the central transverseplane. In the lattercase the inclination of the wires is always in adirection from such central transverse plane.

The angle of inclination at which the wires are set in the clothing maybe varied as required. As a convenient means of applying the wireclothing I propose to wind the barrels of the several napping-rollersspirally, as indicated in Figs. 2, 3, and 4.

By having the inclination of the wires arranged in the manner aforesaidthe tendency is for the cloth to keep its width in passing through themachine.

I claim 1. In a napping-machine, a series of napping-rollers coveredwith card-clothing having the napping-wires inclined in opposite axialdirections, substantially as described.

2. In a napping-machine, a napping-roller covered by card-clothinghaving the wires inelined 0n the same roller in opposite nxizd iionimwuted L0 the cloth is regulated by the directions, substantially asdescribed. speed of thefeedingnleehnnism, snhsinntizdly 10 $3.
